A new species of the tarantula genus Haplocosmia (Araneae, Theraphosidae) from Tibet, China

Abstract Background Haplocosmia Schmidt & von Wirth, 1996 is a small genus distributed in the Himalayas that includes two species. This genus has not been found in China (Li et al. 2021, Yao et al. 2021, Zhao et al. 2022). New information A new species of the genus Haplocosmia is described from China: Haplocosmiasherwoodae sp. n. from Tibet. Photos and a morphological description of the new species are given. The type specimen of the new species is deposited in the Institute of Zoology, Chinese Academy of Sciences in Beijing (IZCAS).


Introduction
The spider family Theraphosidae Thorell, 1869 includes 1031 species in 153 genera, with two species in the genus Haplocosmia Schmidt & von Wirth, 1996: H. himalayana (Pocock, 1899 from the Himalayas and H. nepalensis Schmidt & von Wirth, 1996 from Nepal (Li 2020, World Spider Catalog 2021. Haplocosmia can be distinguished from all Selenocosmiine genera by the undivided spermathecae, thorn-like setae on the chelicerae prolaterally, scopula present on tarsi I-IV, scopula on tarsus IV divided by setae, a procurved fovea, procurved anterior eye row and butterknife-like stridulating setae on the prolateral surface of the maxillae (Schmidt and von Wirth, V. 1996).
Here, one new species of the genus Haplocosmia from China, Haplocosmia sherwoodae sp. n. from Xigaze, Tibet, is reported.

Materials and methods
The specimen was preserved in 75% ethanol. Genitalia were cleared in trypsin enzyme solution to dissolve non-chitinous tissues. The specimen was examined under a LEICA M205C stereomicroscope. Photomicroscope images were taken with an Olympus C7070 zoom digital camera (7.1 megapixels), stacked with Helicon Focus 6.7.1 and processed in Adobe Photoshop CC 2018.
The terminology used in the text and figures follows Bertani (2000) and Sherwood et al. (2021). All measurements are in millimetres. Eye sizes were measured as the maximum diameter from either the dorsal or frontal view. Leg measurements are given as follows: total length (femur, patella, tibia, metatarsus, tarsus).
Abbreviations: A, apical keel; ALE, anterior lateral eyes; AME, anterior median eyes; BL, Basal lobe of retrolateral embolus keel; MOA, median ocular area; PLE, posterior lateral eyes; PME, posterior median eyes; PS, prolateral superior keel. The type material is deposited in the Institute of Zoology, Chinese Academy of Sciences in Beijing (IZCAS).
Female unknown.

Diagnosis
Haplocosmia sherwoodae sp. n. is found at 2356 m elev., in a higher, more montane environment, close to areas of permanent snowfall. (vs. H. nepalensis Schmidt & von Wirth, 1996 which is only known to occur at an elevation of < 1200 m in Kathmandu ( Schmidt andvon Wirth, V. 1996, West et al. 2012

Etymology
The species is named after Miss Danni Sherwood, who confirmed the validity of the new species; noun (name) in genitive case.

Distribution
Known only from the type locality.  Haplocosmia sherwoodae sp. n., holotype, left palp. A prolateral view; B ventral view; C retrolateral view.
